The aim of research during this period has been to study the properties of the optoacoustic effect produced by the photodissociation and recombination of chlorine. We have observed an acoustic response both from time-delayed recombination of the fragments and from the prompt signal due to photofragment recoil and change in mole number of the gas. The data have been fit to theoretical expressions and have been found to agree well with published rates and bond energies. In addition, calculations have been performed to determine the nature of thermal noise in photoacoustic cells. Finally, a prediction of interference in the fluorescence from molecular photodissociation has been made.
